I don't know how any of you can give this guy advice and not give a reference to the statute. So here it is:
http://www.jud.ct.gov/JI/criminal/glossary/assaultweapon.htm
If you read the law, you will see that CT uses 2 sets of criteria to determine if a firearm is an AW.
1) A list of firearms by brand and model. If its on the list, its an AW regardless of how many evil features it has or when it was made. The list includes the term "Avtomat Kalashnikov AK-47 Type"
Keep that in mind its important.
2) A list of "evil features". If your firearm was made before the ban date in 94, then it can have any combination of features. If it was made after that date, it must comply with the limitations of this definition.
A couple of other points:
1) unlike some other states, the gun does not have to have been made into a functional firearm by the ban date to be considered pre-ban. In states like CA, and I believe MA, if a receiver was made prior to the ban, it had to have been built up into a functional firearm before the ban date to be considered pre-ban. Of course, it would be the state's burden to prove it wasn't, but some people get spooked by this.
2) The definition of Avtomat Kalashnikov AK-47 Type" was determined by case law.
In State of CT v Halden Boswell a judge ruled that if a "clone" could interchange partes with a Russian AK, then it fell within the definition of "AK-47 Type".
This means that conversely, if the parts are NOT interchangeable with a Russian AK, which is chambered in 7.62x39, then the firearm is not an "AK-47 Type".
And since there isn't parts interchangeability (specifically bolt and receiver per the case) between 7.62x39 AKs and those chambered in other calibers, those chambered in other calibers are not considered to be AK-47 type.
As such, these rifles are then still subject to the "evil features" portion of the law. So . . what does this mean.
It means that you can have a pre-ban AK with all the evil features provided its not in 7.62x39. The most common of these are the mid 80s Chinese imports chambered in .223
This is my pre-ban Norinco 84s in .223
It also means you can have a post-ban AK provided it has enough of its evil features removed so its not considered to be an AW. This is actually pretty easy since the most common import is the AK-74.
A 74 with a fixed stock only needs to have the bayonet lug removed and the brake that it already comes with permanently affixed. 5.45x39 is a great round and is still pretty cheap.
I hope this helps.
